Engine Light

Had the CAT replaced in February at the local Powerflow center. Engine light has since come on, a CLIP diagnostic test gave fault DF106 - catalytic converter function, garage suggested changing Lambda sensor at an eye watering £240.00.

Is the Lambda sensor likely to solve the issue (albeit finding somewhere cheaper) or am I best to head back to Powerflow and get them to check the CAT as I've only done 3000 miles since it was fitted.

Could be the sensor, but £240 is probably £140 too much to have it changed!

You need to do a live data read on the pre and post cat lambda voltages to diagnose what the issue is before spending beer tokens
